I bought a key blank (without chip) for my ST1300 recently.
I reckon that’s a very good idea. This week I locked myself out of the bike at work. I always start the day with a coffee, and on Tuesday I left the key on the cafe counter. I didn’t notice it was missing until after the cafe had closed, and Ruth had to come and rescue me. Mind you it was nice for once to be the one being rescued.
My ST doesn’t need a chipped key, so a few $10 specials tucked away in strategic places could save future hassle.
